The Israeli army said in a statement that over 80 rockets had been fired from the Strip in the same period. There were no reports of injuries.

It added that it had struck "60 terror sites" across Gaza in response to rocket fire.

During ceasefire talks, Palestinians have insisted that any long-term truce include the end of Israel's eight-year siege on the Gaza Strip, the release of dozens of prisoners rearrested by Israel after being released in 2011, the re-opening of a seaport and airport in Gaza, and the creation of a safe passage between the West Bank and the Gaza Strip.

Members of the Palestinian delegation had warned Tuesday that if Israel continued to "refuse" to make concessions, the ceasefire could collapse.
